Fig. 6

a MGC-containing community profile alongside physicochemical factors for the lake-time group Lake Alinen Mustajärvi_2018-08-22. Colored line charts represent different physicochemical factors, while the gray bar chart on the left depicts the relative abundance of the MGC-containing community. The shaded area indicates the oxic-anoxic transition zone (OATZ). The right stacked bar chart shows the MGC-containing bacterial taxonomy for each sample, with colors representing different taxonomic lineages. Duplicate samples are marked with a left square bracket and an asterisk. b Relative abundances of MGC-containing communities in samples from different niche zones: oxic (n = 8), hypoxic (n = 99), and anoxic (n = 24). c Density plot showing the distribution of dissolved oxygen levels in samples containing putative alphaproteobacterial and deltaproteobacterial MTB. d Abundances of putative alphaproteobacterial and deltaproteobacterial MTB in hypoxic and anoxic zones. For (b, d), boxplots display the first quartile, median, and third quartile of abundance distribution values, with whiskers extending 1.5 × interquartile range. Dots represent individual abundance values.
